How to propagate Photinia serratifolia for high survival rate
Today, the editor will introduce the related introduction of how to propagate Photinia serratifolia for high survival rate and the key points of cutting propagation techniques of green plants and flowers. Next, the editor will provide you with detailed answers.
Photinia serratifolia is mainly distributed in the subtropical regions of Southeast Asia and North America, and it is also widely cultivated in many provinces of China. Photinia serratifolia is suitable for growing in a warm and humid environment and will be more vibrant under sunlight. It has strong drought resistance and shade tolerance and is suitable for growing in slightly acidic soil. The main method of propagation is cutting. Let's learn about the cutting techniques of Photinia serratifolia from aspects such as cutting time, branch treatment, cutting methods, and planting maintenance.
1. Cutting Time
The suitable temperature for cutting Photinia serratifolia is between 20°C and 30°C. Therefore, the cutting time for Photinia serratifolia is mostly between April and June every year, as the climate is warm and suitable during this period, which is conducive to the rapid rooting and sprouting of Photinia serratifolia after cutting. Alternatively, cutting can also be performed between August and October, as the temperature is also relatively suitable for the growth of Photinia serratifolia.
2. Branch Treatment
The branches selected for cutting can be the current year's branches or semi-woody tender branches. The branches should be cut to 3-4 centimeters in length, preferably with a leaf bud, and then soaked in a properly diluted rooting hormone for an hour. After removal, they can be cut for propagation.
3. Cutting Process
Insert the treated branches into the soil to a depth of 3 centimeters, then cover the surrounding soil and press it down, and water thoroughly. The moisture content in the soil should be maintained at 60%. After about 15 days, Photinia serratifolia will root and sprout.
4. Planting Maintenance
After cutting, the watering amount, light intensity, and fertilizer dosage of Photinia serratifolia need to be controlled. The watering amount should ensure sufficient water supply for the plant growth while avoiding waterlogging and root rot. After half a month, it is necessary to appropriately reduce the water content in the matrix to maintain it at 40%; when the sunlight is too strong, shading should be provided to avoid scorching the leaves; fertilizing should follow the principle of applying thin and frequent fertilizers; and it is necessary to prevent diseases and pests. If diseases and pests have already appeared, they need to be sprayed with medication.
The above sharing on how to propagate Photinia serratifolia for high survival rate and the specific introduction of Photinia serratifolia cutting propagation techniques are hoped to bring some knowledge of flowers to green plant enthusiasts.
